path as related to the "exec" function

[pauls]

Hi,
I am trying to start another program from within PERL useing "exec"

The problem arises due to, I think, a space in a pathname as follows:

exec("d:\\programfiles\\fred\\program v10.1\\wefit.exe plot.dat");

I am trying to start the program "wefir" on the file "plot.dat"

You'll notice how part of the path to the executable includes a space in
one of the directory names.

If the "wefit" file is located in a directory without a space in the
directory name the above type of code of works fine. But, I am stuck
with the space in the pathname (for now) and need a work around.

Anyone have any helpful thoughts on this?

Thanks!

Paul

Quote the path:

exec('"d:\programfiles\fred\program v10.1\wefit.exe" plot.dat');

Hello Gunnar,
That did the trick. Thank you very much for your help, I appreciate it!

Quote the path:

exec('"d:\programfiles\fred\program v10.1\wefit.exe" plot.dat');

Or avoid the shell altogether:

exec('d:/programfiles/fred/program v10.1/wefit.exe', 'plot.dat');
